Abstract: 362,739. Newspaper &c. assembling machines. WINKLER, A. and DœNNEBIER, M., Neuwied, Germany. Jan. 20, 1931, No. 1944. [Class 100 (i).] In apparatus for stuffing or assembling newspapers or the like of the kind in which a moving blade engages the folds of the sheets to be associated, the blade is provided with means whereby it can pick up unfolded sheets. The blades 1, Fig. 1, are fixed to a rotarv carrier 7 and move over a table 28 to which folded sheets are supplied at stations I .. VI as shown. The inner corners of the folded sheets are lifted by suction or other apparatus so as to allow the blades to enter therein, and two rotarygripper delivery-devices 3 are provided so that two sets of three assembled folded sheets can be delivered or, if one device 3 is inoperative, one set of six assembled sheets. If it is desired to insert an unfolded sheet within each set of six folded sheets, the unfolded sheets are fed at an additional station VII, and a further station VIII is provided for use when the double-delivery is employed, means being provided on the blade 1 to enable it to pick up the unfolded sheet. In one form, Fig. 4, each blade 1 is hollow with suction openings 10 on the upper surface. Openings 14 in the carrier 7 communicate with the interior of the blades and also, at the requisite times, with grooves 18 suitably situated on the table 28 connected to a suction pump so that as the blade 1 and sheet C arrive in the relative positions shown in Fig. 3 at the station VII or VIII, suction is applied to the blade 1 and it grips the sheet. On its further travel it carries the sheet C into the folds of the sheets fed at the succeeding stations. In another construction adapted to pick up unfolded sheets only, if desired, the leading edge of each blade 1 has a number of slits 34, Fig. 6, through which pass needles 31 which are clamped to the blade by a plate 32 with their points projecting a small distance below the undersurface of the blade. At each station where an unfolded sheet C is to be picked up, the table 28 is provided with a hinged flap 36 having slits to accommodate the projecting points of the needles 31. When a sheet C is deposited at its station on the table 28, the flap 36 is raised by mechanism 39, 40 so that the front edge of the sheet lies in the path of the projecting points and is pierced thereby. In a third form, Fig. 9, the blade 1 has gripping means consisting of a bar 45 mounted on a spring-controlled hinge 44 at one end of the blade and actuated by a cam-operated crank arm 47 so as to grip the sheet C when it is situated slightly in advance of the blade. The sheet C is fed at a slightly greater speed than the blade for this purpose. Pile tables for sheet feeds ; sheet-separators ; sheet-forwarders ; sheet-guides.-The sheets S are supported on rollers 21 and a projecting ledge 22 in a receptacle 20 and the front edge of the bottom sheet C is bent downwardly by suction nozzles 23 pivoted about one of the rollers so as to rest against a roller 24 divided transversely to allow the nozzles to descend. The bent-down edge of the sheet enters an aperture 25<1> in a roller 25 rotating in the opposite direction to the roller 24 so that on further rotation of the rollers the sheet is gripped between them and drawn from the stack. Sheet guides 26 direct the sheet to the collecting station and rollers 27 thereon co-operate with the roller 24 to ensure that its movement is not stopped when the aperture 25<1> is again adjacent to the roller 24.
